Troubleshooting Our 2JZ Head Digitization on our Centroid 5 Axis CNC

- The Centroid CNC is here! Learning is fun, challenging and rewarding. Dave walks you though some of the setbacks we have had trying to learn the machine. It is not easy! Was the team victorious?! Have to watch and see!!

Nick at Perfect Circle is great guy and smart dude!!
Really impressive looking result! I must be missing something. Would you please explain why the machine can't digitize the ports without clay? It's obviously a very capable machine. It's not obvious (at least not to me) why it can't simply digitize the port in "one" pass rather than doing it one half at a time using clay. Thanks.
@@darylmorse watching it now, and we missed an entire clip explaining why it needs clay!
The prob wouldn’t know to go down one side if the divider and come back out and do the other side so you have to clay one side and it basically treats each valve or half as 1 port. So you digitize one side and mirror the other or digitize the other side and bring them together in mastercam.
@@headgames Thank you for the explanation. That makes sense.
Whats up Dave it's me Melvin I can't wait to see the head when it's done
I would think you would want a smoother surface on the combustion chamber for the sake of reducing exposed surface area and hence heat transfer. Is it not that big of a deal in your experience?
@@rafaellastracom6411 have not experienced any difference
WTH is up with that head just before 5 min? Finished head is beautiful
@@slfrules1 that was the issue with the clay
Except for the cost it would be wonderful to have a head ported and put on the flow bench and have cams made to match the head. Once you get it sorted I expect that machine will be running all day every day.
@@robertfontaine3650 that’s why we don’t do big ports and big valves. It wouldn’t work for 90% of the cams available.
flow numbers bro! sho us that!!
show hand port vs cnc flow numbers
show us an excessivly ported head compared to a correct ported head for thos that beleive bigger is always better.
show us a port thats more than 90% under the seat. here in sydney some shops just make that area as wide as the seat, i would love to prove them wrong
@@GTRliffe you do a hand port and digitize it for cnc porting.
The throat diameter sounds like a fun idea
The rest of what you said is a whole bunch of work lol
Looking great Dave! Bryan from SAM says hi!
@@southerndualsport3827 hey Brian!
@@headgames It's funny we are trying to buy that exact machine for our harley heads. I'm running a 4 axis right now doing air intakes and stuff for a buddy in north Alabama. Finally got out of Cali.
@@headgames glad to see you're doing good bud!!
Uh, I ain’t getting it…
If the material ain’t there to cut, on the scanned original, clay ain’t going to add material to cut, on the production piece.
I get it, that the clay is a mask for the scan, and is the part where this is where blending comes in, but, tend to think the clean up on the production piece leads to localized increase in CSA, inconsistency, port to port
Back in the day, head people with the connections, would actually end up going to the foundry, to “rub” cores, to add material in hollow / depressed areas. Any chance of having the castings modified, instead of compromising your porting to the existing casting, or are you using used OEM cores? What about welding, as the problem area seems minimal?
I realize the whole “existing architecture” has been the bane of cylinder head people from the beginning.
Great work and thanks for sharing…
@@georgedreisch2662 the issue with the clay I realize now is missing a clip in the front of the video explaining why and how that happened.
The clay just gives the prob someplace to not go. And is also the most important part of the digitization. Get it in the wrong area, wrong texture and you pay for it in time at post processing.
The small amount of material that we blend into the port doesn’t matter. It’s there to begin with really, we are just scratching it so it looks better.

hey Dave!
how was your holiday? 😊
@@BraapSupport great!
@@headgames I am happy for you!
No who needs clay if you don’t have Dimples 😶
